BACKGROUND
[0001] Physiological data, including for example, oximetry data, can be useful for monitoring
the health of a patient or the health of a particular organ. Currently available technology
for acquiring oximetry data, however, is limited in many ways and is inadequate to
satisfy the demand for cost-effective health care.
[0002] US2008/0208023 discloses a physiological sensor device having a foldable portion carrying a sensor
and designed to be deformed around the tip of an appendage of a patient and a wrapping
tail extending from a front portion of the foldable portion.

that can be fitted to a patient and discarded after use. The apparatus can include
a wireless communication module that allows communication with a remote device. The
remote device can include a monitor, a display, a storage device, or other module.
The apparatus can include an oximeter measuring device having a sensor module that
generates data corresponding to pulse oximetry or regional oximetry. The apparatus
includes a flexible structure that can be conformed to provide a close fit on a patient
and
wirelessly provide medical data to a remote device. After collecting oximeter data
or other data while fitted to a patient, the apparatus can be discarded.

DETAILED DESCRIPTION
[0014] FIG. 1 illustrates system 5 including device 10A in an un-folded configuration. The
apparatus includes a structure that can be deformed to accommodate a hand shape, for
example. One example includes a pliable membrane including a plurality of foam (polyurethane)
layers in a laminated arrangement. A layer in contact with the tissue can be open-cell
foam (for patient comfort) and an outer layer can include a closed-cell foam (for
ease of cleaning).
[0015] Device 10A, in the example illustrated, includes a plurality of apertures including
ventilation holes 14. Ventilation holes 14 are sized and distributed to provide circulation
to the underlying tissue site, provide breathability, and prevent overheating of the
user. In addition, apertures 16A and 16B are sized and distributed to provide clearance
for a finger or other tissue. In the example shown, aperture 16A and aperture 16B
are separated by bridge 32.
[0016] Device 10A includes a sensor module, here depicted to include distributed components
including sensor element 12A, sensor element 12B, and sensor element 12C. In other
examples, the sensor module is a unitary component that includes a sensor and associated
circuitry in a single package. In the example shown, sensor element 12A includes an
optical emitter and sensor element 12B includes an optical detector. Sensor element
12A and sensor element 12B are configured to provide light at a particular wavelength
and detect light in order to generate a signal suitable for photoplethysmography.
For example, the sensor module can generate a signal corresponding to pulse oximetry
or tissue oximetry (regional oximetry). Sensor element 12A, sensor element 12B and
sensor element 12C are coupled, in the example shown, by electrical conductor 12D.
[0017] Device 10A also includes communication module 20A. Communication module 20A is coupled
to sensor module by electrical conductor 22. Electrical conductor 22 (as well as conductor
12D) can include a flexible conductor, such as braided wire, litz wire, or other multi-strand
wire.
[0018] Communication module 20A can include, in various example, a transmitter, a receiver,
or a transceiver. Communication module 20A can include a radio frequency (RF) circuit,
an infrared (IR) device, an ultrasonic device, or other wireless communication module.
In one example, communication module 20A includes a BLUETOOTH transceiver or other
such device configured for ad hoc wireless communication using a peer-to-peer or other
networking configuration.
[0019] In the example shown, communication module 20A and the sensor module are powered
by power supply 24. Power supply 24 can include a battery, a fuel cell, an energy
storage device, or other portable power source. Power supply 24 is controlled by switch
30. Switch 30 can include a manually operable switch such as a removable tab that
connects the power supply to a circuit of device 10A. In one example, switch 30 includes
a physically releasable contact.
[0020] In one example, power supply 24 is controlled by a power management module. The power
management module can be included in communication module 20A, power supply 24, or
other circuitry of device 10A.
[0021] In one example, the power management module is configured to detect the presence
or absence of a user. For example, a mechanical switch, a capacitance-based detector,
a resistance-based detector, or other type of device can be configured to sense the
presence of device 10A affixed to a user, and deliver current from power supply 24
as appropriate.
[0022] Device 10A can include a processor module disposed in any of the sensor module, the
communication module, or other component. The processor module can be configured to
receive an output from the sensor module, execute an algorithm using a processor and
a set of instructions to determine information regarding the physiological parameter
and provide the information to the communication module for forwarding to the remote
device.
[0023] In one example, the remote device provides instructions for execution by the wearable
device, hi such an example, the processor module executes instructions to implement
the changes or perform analysis or calibration as requested by the remote device.
In one example, the wearable device includes memory for storage of instructions and
data for use by the wearable device.
[0024] In one example, one or more of the electrical components (such as the sensor module,
the communication module, a power management module, a processor module) is electrically
shielded. Electrical shielding can isolate the various components and provide patient
protection. Shielding can include measures to prevent or reduce electrostatic shock,
reduce stray currents, and provide electrical isolation with respect to the tissue.
[0025] Device 10A also includes strap 26. Strap 26 is configured to at least partially encircle
a portion of a user, such as a wrist, ankle, or other tissue. Strap 26 includes a
fastener mechanism, shown here as distributed as fastener portion 28A and fastener
portion 28B. Fastener portion 28A and fastener portion 28B can include, for example,
a buckle, or a hook and loop type fastener (sometimes referred to as Velcro).
[0026] Device 10A includes relief features 18. Relief features 18 are depicted as triangular
shaped cuts; however a lateral slit or other configuration can also be used. Relief
features 18 allow the finger portion of device 10A to flex in a side to side direction
with movement of the finger relative to the wrist portion. In addition, relief features
18 allow repositioning of the finger portion of device 10A without disturbing strap
26. In the figure, the sensor module is aligned to detect a physiological parameter
associated with the index finger. In addition, relief features 18 allow the finger
portion to be repositioned to align with any other finger, such as the ring finger.
[0027] FIG. 2 illustrates a view of hand 8 with device 10B in position on the index finger.
Ventilation holes 14 are visible in the finger portion. In addition, bridge 32 is
illustrated below a portion of the finger. Strap 26 is shown encircling the user's
wrist.
[0028] FIG. 3 illustrates device 10B in communication with remote device 40. In this view,
a portion of the finger is visible atop bridge 32. Ventilation holes 14 provide cooling.
The wrist (not shown) is encircled by strap 26.
[0029] Device 10B includes semi-rigid structural member 6. Structural member 6 can include
a malleable wire that is embedded in or affixed to the pliable membrane of device
10B. In this example, structural member 6 can include two separate wire elements or
a contiguous wire element with a bight at the fingertip region (not visible in this
view).
[0030] Communication module 20B is affixed to a surface of device 10B and in this example,
includes a wireless communication module such as an RF transceiver. As denoted by
communication link 46, communication module 20B enables wireless communication between
device 10B and remote device 40 (via antenna 42). Antenna 42 can include a radio frequency
(RF) antenna. In one example, remote device 40 and device 10B communicate wirelessly
using an infrared link.
[0031] Remote device 40 can be configured to exchange information corresponding to tissue
oximetry, pulse oximetry, or other physiological parameter. Remote device 40 can include
a memory or other data storage device as well as a processor. In addition, remote
device 40 can include various types of software, firmware or hardware including, for
example, a printer, a display, a network interface, or a user interface.
[0032] FIGS. 4A, 4B, and 4C illustrate a durable, disposable wireless device suitable for
use in monitoring a physiological parameter associated with the thenar eminence. In
FIG. 4A, hand 8 is shown with palm-up and is partially encircled (or wrapped) by conformable
device 10C. Device 10C is configured to position sensor module 12D atop thenar eminence
(bounded by line 52). Sensor module 12D is coupled by electrical conductor 22 to a
module on an opposite side of the hand.
[0033] In FIG. 4B, hand 8 is shown with palm-down and electrical conductor 22 is coupled
to communication module 20C. Communication module 20C and power supply 24 are visible
on this side of the device 10C. Ventilation holes 14 are also visible in the portion
shown in FIG. 4B. In one example, device 10C is held in place by the contours of the
tissue surface formed by the thenar eminence. In one example, an adhesive is used
to bond hand 8 and device 10C.

Sensor module 12E is electrically coupled, via conductor 22, to communication module
20D. Communication module 20D and power supply 24 are located on strap 26. Strap 26
is configured to encircle a wrist of a user.
[0035] FIG. 5 illustrates method 56 according to one example. Method 56 includes, at 58,
providing a wearable device. The wearable device includes a pliable membrane having
a semi-rigid structural member. The pliable membrane can be configured to conform
to a tissue surface. The semi-rigid structural member can include a malleable wire
that maintains the shape of the pliable membrane. The wearable device includes a sensor
module and a wireless communication module. At 60, the device is affixed to a user.
The device can be affixed by manipulating the pliable membrane (along with the semi-rigid
structural member) to conform to the tissue surface.
[0036] At 62, method 56 includes configuring a remote device to receive data from the wearable
device. The data can be received and stored, or printed, or processed, or displayed
or forwarded using a network interface.
[0037] Additional configurations or variations are also contemplated. For example, the sensor
module (or the communication module) can be affixed to a surface of the pliable membrane
or embedded within a layer (or between layers) of the membrane.
[0038] The device can be configured for disposal. For example, a low cost transceiver and
sensor can be used with a foam-based pliable membrane. As such, the device can be
configured for single patient use. The device can be used on a single patient and
discarded thereafter. In one example, the device can be configured for continuous
use of several days. For example, the foam laminate of the pliable membrane can have
a surface suitable for direct contact with the patient tissue and a surface suitable
for moisture release. The device can be configured for comfortable wear on a single
patient for several days. In one example, the device can be repositioned to align
the sensor module with a different finger or a different toe and is suitable for approximately
4-days use.
[0039] In one example, the sensor module and the communication module are housed within
a single package. In addition, the package can include hardware, firmware, software
and sensing elements, as well as power management unit, a battery, a power-on mechanism,
as well as a wireless transceiver.
[0040] The device can be configured to acquire data continuously, periodically, or intermittently.
For example, one configuration provides that upon actuation (of switch 30), the device
continuously records and transmits data corresponding to a physiological parameter.
In one example, the data is stored within the device and forwarded according to a
schedule, or upon request, or upon detection of a particular event.
[0041] In one example, the pliable membrane (along with the semi-rigid structural member)
provides protection for the electronic circuitry (including the sensor elements, the
communication module, power management module, and the battery).
[0042] The pliable membrane can be deformed to conform to the shape and contour of a finger,
a toe of a patient or other user. The pliable membrane can include a malleable structure
configured to maintain a particular shape. The structure can include a semi-rigid
component including, for example, a soft wire or metal spine to maintain the formed
shape. For example, a perimeter wire embedded in the laminations or affixed to a surface
of the foam can be used to retain a particular shape.
[0043] A wrist portion is provided to encircle the patient's wrist and to stabilize the
apparatus when installed. The wrist portion can also be used to encircle an ankle
or other body portion of the patient. The wrist portion can include a hook- and-loop
type closure, an adhesive region, or other attachment mechanism.
[0044] A power supply is located near the wrist portion in the example shown. The power
supply can include a battery. In the example shown, the power supply includes a pull
tab that actuates an electrical switch to energize the apparatus with electrical power.
[0045] The example shown also includes a circuit module located near the power supply.
[0046] An electrical conductor carries current between the various modules.
[0047] Strain relief elements are provided along the length of the base structure. In the
example shown, the strain relief elements include v-shaped notches along edges of
the foam laminate. The notches allow the finger portion of the base structure to be
affixed to any of the fingers while the wrist portion encircles the patient wrist.
[0048] Various types of strain relief elements are contemplated. In addition to v-shaped
notches, the strain relief can include one or more transverse slits along the edges
of the foam laminate. In one example, the strain relief elements are omitted and the
length portion of the base structure is twisted by approximately 90 degrees to accommodate
different fingers for the finger portion. The strain relief can accommodate re-positioning
of the finger portion of the apparatus to mitigate tissue degradation (damage) at
a sensor site.
[0049] According to one example, a pair of finger apertures is provided at the finger portion
of the pliable membrane. The finger apertures are separated by a bridge portion of
the base structure. When positioned on a patient, the bridge portion can be configured
to pass beneath the finger and the finger can be passed through the finger apertures.
[0050] A plurality of vents is provided in selected locations of the pliant membrane. The
vents enable the tissue to breathe and dissipate heat or moisture.
[0051] In one example, the finger portion includes sense elements. The sense elements can
include any number or combination of an optical emitter, an optical detector, a temperature
sensor, a pressure sensor, an accelerometer, or other sensor tailored to provide data
concerning a physiological parameter.
[0052] A fold relief opening in the finger portion can be aligned with an end of the finger
and ease formation of the fitted apparatus about the patient.
[0053] The pliant membrane maintains the sense elements in a relatively fixed alignment
and position with respect to the tissue and other elements of the system. In one example,
the sense elements include any combination of transmission or reflectance-based sensors
that can provide regional oximetry data.
